Test conditions and notes4
- 1. All parameters NOT specially mentioned are measured at 48VDC input, rated load and 25℃ of ambient temperature.
- 2. Ripple & noise are measured at 20MHz of bandwidth by using a 12" twisted pair-wire terminated with a 1uf ceramic & 10uf tantalum capacitor across output.
- 3. The power supply need to connect "+Vout" to "+R.S" and "-Vout" to "-R.S".
- 4. The power supply is considered a component which will be installed into a final equipment. The final equipment must be re-confirmed that it still meets EMC directives. For guidance on how to perform these EMC tests, please refer to “EMI testing of component power supplies.”

FAQ
Can I use the MHB150-48S12 to run 12V industrial control equipment from a 48V-class power source?
This converter accepts 36-75V input and provides a constant 12V output, which matches systems stepping down from a 48V-class bus. It is rated for 150W total output with up to 12.5A available at 12V.
Is this a good fit for 12V automation accessories inside a compact machine enclosure?
The 61.0 × 57.9 × 12.7 mm size supports use where board area and height are limited. On the electrical side, it delivers constant 12V output up to 12.5A with a 150W rating.
Can the MHB150-48S12 power 12V embedded or industrial PC peripherals in harsh temperature conditions?
The specified operating case temperature range is -40°C to +100°C, with thermal shutdown at 100°C ±5°C case temperature, so proper derating or cooling is needed. It provides a constant 12V output with up to 12.5A available from a 36-75V input source.
Would this converter work for 12V instrumentation or monitoring modules on a 36-75V DC system?
It is intended for 36-75V input systems that need a regulated 12V rail. With 150W capacity and 12.5A output current, it fits 12V instrumentation or monitoring loads that stay within those limits.
Is this model suitable for outdoor or washdown installations?
The provided data lists an operating case temperature range of -40°C to +100°C, but it does not list an IP rating. Based on the stated specs, temperature capability is defined, while exposure to water, dust, or washdown is not specified.
